What I claim as my mvention'and desire to secure by Letters Patent of the United States of'America is The combination with a vehicle having a framework or chassis, a tipping platform for supporting a load pivot-ally mounted on said framework, a roller rotatably mounted on said framework,- said roller having its periphe horizontal plane of, tile located below the form when said platform is in its non-discharging position and the periphery of said roller projecting above the plane of said floor when said platform is moved to discharging position.

In testimony whereof, I have signed my LEON FQNTAINE.
